5.  Touch and hold one ohmmeter probe to the C (common) terminal, then 

touch and hold the other probe to the R (Run) terminal. The ohmmeter 
should show a reading of 3Ω 

± 10%. If not, the compressor is bad.                                         

6.  Touch and hold one ohmmeter probe to the C terminal, then touch and 

hold the other probe to the S (Start) terminal. The ohmmeter should show 
a reading of 11Ω 

± 10%. If not, the compressor is bad.                                                            

7.  Touch and hold one ohmmeter probe to the R terminal, then touch and 

hold the other probe to the S terminal. The ohmmeter should show a 
reading of 14Ω 

± 10%. If not, the compressor is bad.  

8.  Touch and hold one ohmmeter probe to the C, or R or S terminal, then 

touch and hold the other probe to the ground on the compressor. The 
ohmmeter should read infinity. Any resistance indicates a shorted 
compressor. 

9.  If the compressor tests ok, but does not start, check start relay, overload 

protector and live voltage. 

 
B.  Live Voltage 
 

1.  Unplug WINEMATE cooling unit or disconnect power.  
2.  Remove the terminal cover from the compressor 
3.  The WINEMATE unit needs to be plugged in and turned on.  
4.  Locate the terminals on the start relay and the overload protector.   
5.  Set the voltmeter to the AC 200 scale.  
6.  Touch and hold one voltmeter probe to the terminal on the start relay, then 

touch and hold the other probe to the terminal on the overload protector.  

7.  The voltmeter should show a reading of 115 volts. 
8.  If the test is good and the compressor does not start, check the start relay, 

overload protector, and measure the resistance. 

 
 

A start relay’s function is to energize and de-energize the compressor’s start 
winding.  The coil of the current type relay is connected in series with the run
